Hello! A lot has happened on the Vector/Function/<backend>Vector interface the last weeks. For clarity, I would like to have a little "summing up" thread. That is, I think it would be beneficial to explicitly show how the new interface is intended to be used. Sounds good? Here are some situations, to which I propose solutions. Please correct if these are not in line with the intended interface, or if there are better ones.
How to: *) Get reference to Vector from a (discrete) Function u Vector& v = dynamic_cast<Vector&>(u.vector()); *) Get reference to uBlasVector from Vector v: uBlasVector& uv = dynamic_cast<uBlasVector&>(*v.instance()); *) Get reference to PETScVector from Vector: ??? *) Get reference to uBlasVector from (discrete) Function u uBlasVector& uv = dynamic_cast<uBlasVector&>(*u.vector().instance()); *) Get reference to PETScVector from (discrete) Function u ??? Please add more situations and suggestions. Thanks! /Dag _______________________________________________ DOLFIN-dev mailing list [email protected] http://www.fenics.org/mailman/listinfo/dolfin-dev
